The Antikythera mechanism is an ancient mechanical computer designed to calculate astronomical positions. It was recovered in 1900–1901 from the Antikythera wreck. Its significance and complexity were not understood until decades later. Its time of construction is now estimated between 150 and 100 BC. Technological artifacts of similar complexity and workmanship did not reappear until the 14th century, when mechanical astronomical clocks were built in Europe.

The mechanism is the oldest known complex scientific calculator. It contains many gears, and is sometimes called the first known analog computer, although its flawless manufacturing suggests that it may have had a number of undiscovered predecessors during the Hellenistic Period. It appears to be constructed upon theories of astronomy and mathematics developed by Greek astronomers and it is estimated that it was made around 150-100 BC.

“Ever the winds blow; ever the grass grows. Every day, men and women, conversing, beholding and beholden. The scholar is he of all men whom this spectacle most engages.”
Ralph Waldo Emerson, "The American Scholar"

The practice of Centering Prayer is basically a waiting upon God with loving attentiveness, fulfilling the Gospel injunction, “Watch and Pray.” If one can accept the notion of prayer as primarily relationship with God, it becomes obvious that one’s relationship with God can be expressed without words, simply by a gesture or even by one’s silent intention to consent to God’s presence.

"What amazed and upset him most of all was that the majority of people of his age and circle, who had replaced their former beliefs, as he had, with the same new beliefs as he had, did not see anything wrong with it and were perfectly calm and content. So that, besides the main question, Levin was tormented by other questions: Are these people sincere? Are they not pretending? Or do they not understand somehow differently, more clearly, than he the answers science gives to the questions that concerned him? And he diligently studied both the opinions of these people and the books that expressed these answers." - Tolstoy, "Anna Karenina"

"They do not covet truth, but victory and the dispelling of their own doubts. What they defend is some system, that is, some view about the totality of things, of which men are actually ignorant. No system would ever have been framed if people had been simply interested in knowing what is true, whatever it may be.” - George Santayana

“The old grey donkey stood by himself in a thistly corner of the Forest… and thought sadly to himself, “Why?” and sometimes he thought, “Wherefore?” and sometimes he thought, “Inasmuch as which?” and sometimes he didn’t quite know what he was thinking about.” — Eeyore
